4.1.3. Examples

Try these first

1. 1.

   What are dead loads?

   Hint

   Think about what the building consists of.

2. 2.

   Give an example of a live load.

   Hint

   Consider things that are not permanent.

3. 3.

   What is a dead load?

   • Variable weight over time
   • Fixed weight of a structure
   • Wind force

   Hint

   Recall the definition of dead and live loads.

4. 4.

   True or False: Live loads remain constant over time.

   • True
   • False

   Hint

   Think about people and furniture varying.

5. 5.

   A structural engineer analyzes a four-story building. If the dead load is estimated to be 200,000 lbs and live loads expected during peak usage are 150,000 lbs, what total load must the builder design for?

   Hint

   Add both types of loads together for the total.

6. 6.

   A building experiences 10 mph steady wind. Calculate the expected wind load if its surface area exposed to wind is 500 sq ft, knowing wind pressure is typically 0.0024 x (velocity^2).

   Hint

   Use the formula given with the surface area.
